Advanced and Versatile Digital Whiteness Color – Enviro Testers 

Overview

The whiteness degree instrument with the digital display is mainly applicable for the measurement of the whiteness degree on the surface of the object or the powder in the white color and the color close to white. The whiteness degree can be accurately reduced that is consistent with the visual degree. The opacity degree of the paper can also be accurately measured. 

This instrument can be widely applied for the measurement of the whiteness degree of the objects like textile & printing & dying, oil paint & dope, chemical construction material, paper & paper plate, plastic product, white cement, ceramics, porcelain enamel, porcelain clay, French chalk, starch, flour, salt, wash, and cosmetics, etc.  

 

Features

• Adopt the quality imported & original components, with the high-efficiency & low-spoilage circuit, and with the good reliability
• The configuration with the high-automatic & multi-function microcomputer, equipped with the RS232 serial communication interface to connect the printer.
• The outstanding color-measurement performance is very accurate. Adopt the CAD, and the overall spectrum characteristics of the instrument comply with the responding curve of the CIE standard observer, and can accurately obtain the ISO whiteness degree.
• The imbedded clock memory & storage system can store the measurement & correction data in real time, and can store and transfer 20 groups of the measurement data for long time, and can be used for the historic reference.
• The quick automatic correction, with the prompt of the self-diagnosis information, rapid and stable response, reliable maintenance-free operation.
